" Your image will be resized if needed to a maximum dimension of 200 pixels width x 500 height automatically, but your image file should not exceed 2000 KB.

By clicking "Register", you certify that you have the right to distribute this photo. "

If all you want to do is hide it use firebug or if using Chrome just right click on that message and inspect element and find the div tag, then just add display:none in your css file for that tag.
